Cyclic Corrosion Test Chamber

ISO 11997-1, Ford CETP, VW PV 1210, GMW 14872, SAE J2334

In cyclic corrosion tests, samples are exposed to different environments in a repeating cycle. These tests simulate all the environments a product may encounter over its lifespan or quality assessment. They provide information about the durability of coatings applied based on the aggressiveness and requirements of the products.

Simple tests consist of two cycles: spray and drying. More complex procedures (especially for automotive tests) require multi-stage cycles, including salt spray or shower functions in addition to moisture and drying.

Test standards recommend testing finished products because areas such as weld zones, corners, internal holes, and joints are where corrosion is most likely to occur and where evaluating coating performance is most challenging. Therefore, it is important to test finished products for both the manufacturer and the customer, as long as the size of the parts allows for it.

Cyclic corrosion tests are performed in specialized cabinets with multiple functions and features.

Our cyclic corrosion test chambers are equipped with a PLC control system, allowing you to set and record the desired cycles. This enables you to track and control the steps of the test cycle and also obtain a graphical representation of the test process.

To operate this device, the following systems are required:

• • Deionized water unit (1-2 L/h flow rate, providing 5 μs/cm conductivity)

• • Air compressor (providing 6-8 bar pressure)

• • Water drainage system (for discharging saltwater)

• • Exhaust outlet (10 cm diameter, opening to the outside atmosphere)
